Boele-TRUCK Fon ROLLING-STOCK.

SPECIFICATION forming part of Letters Patent N0. 757,927, dated April19, 1904.

Application filed October 5,1903.

To all whom it 77mg/ concern..-

Beit known that I, HENRY ALBERT HOY, a subject of the King of GreatBritain and Ireland, residing at Bolton, in the county of Lancaster,England, have invented Improvements in Bogie-Trucks for Rolling-Stock,of which the following is a specification.

This invention has reference to improvements in the construction ofbogie-,trucks for rolling-stock whereby the load to be carried can betransmitted to the axles of the bogietruck in a more advantageous mannerthan heretofore and the transmission of .vibration from the axles of thetruck to the body of the vehicle carried thereby can be reduced, theconstruction, moreover, being specially adapted for use with electricmotors.

In a bogie-truck according to this invention the bogie-frame issupported through springs by longitudinal beams that are connected tovertically -movable supports, between which and the axle-boxes on thewheelaxles other springs are interposed. The bogieframe may be provided,as usual, with a bolster, to which the load is directly applied andwhich is supported on springs carried by a lower transverse beamsuspended from the bogie-rame, so that in this case the load will betransmitted to the axles of the vehicle through three sets ofvertically-acting springs.

Bogie-trucks according to this invention can be constructed in variousforms, and the springs used therein maybe of any of the i kindsheretoforecommonly used,'such as coilsprings, laminatedcarriage-springs, or indiarubber springs, or partly of one kind andpartly of another.

The invention consists in various novel features of construction and incombinations and arrangements of parts, all as hereinafteizmoreparticularly described,and pointed out in the claims. y l

IIn the accompanying illustrative drawings, Figure l shows partly inside elevation and partly in central longitudinal section, and Fig.

2 in plan, one construction of bogie-truck according to this invention,Fig. l also showing in side elevation a pivotal platform or support forcarrying one end of the underframe and body of the vehicle with whichthe bogieserai No. 175,846. on model.)

. partly in end view and partly in cross-section,

on the line A A of Fig. l. Fig'. 4 is a crosssection of the bogie-truckand pivotal platform or support, taken on the lineB B of Fig. 1.

In the construction shown the bogie-t'rame comprises two longitudinalside members or sole-bars a of angle-section, each provided on its outerside with two horn-plates with axlebox guides c and a spring-holdingbracket Z and connected together at the central portion of their lengthby two transverse members or transoms e and a top plate f. The ends ofthe two sole-bars are iirmly connected together by bent end pieces f.The transoms e comprise vertical plates of angle-section connected tothe sole-bars a. by angle-irons g'and'spaced at a suitable distanceapart to accommodate the bolster L, which is placed between them andprovided with laterally-arranged vertical bearmg-piecesc, arranged towork between similar vertical bearing-pieces m, fixed on the transoms e.

The top plate f, which is curved at its opposite ends and extended atits sides in a longitudinal direction, so as to impart increasedstrength tothe bogie-frame, is formed with a central opening a and withtwo lateral openings 0, through which respectively extend the bogiecenter p and lateral bearing-pieces q, that are carried by the bolster hand upon which a center piece r and lateral bearingpieces s on aplatform or support tto' be connected to the underframe or body of thevehicle to be carried respectively bear and move in the ordinary way.

/L is the pivot-pin for connecting the center pieces p and r together inthe ordinary way. The bolster la. is of box-like section built up oftransverse pieces of channel-iron and top .and bottom plates and issupported at its ends upon two pairs of coiled springs u, carried by atransverse beam c, which may, as shown, be oi' channel-section and issupported at its ends by longitudinal bars w, carried by the lowerslotted ends l of two pairs of links 1, the upper ends l of which arejointed at 2 to the transoms e. The upper and lower ends oi' thespringsu are arranged to respectively IOO bear directly against bearing-plates3 and 4, that are fixed to the lower sides of the bolster /i andtransverse beam Q) and are provided with vertical extensions 5, thatenter the said coiled springs and hold them in position laterally. Thelongitudinal bars w, that carry the ends of the transverse beampreferably engage in V-shape bearings 6, formed on the under side of thelower bearing-plates 4 and so arranged that the lower ends of the twopairs of links 1 are spaced farther apart than their upper ends, asheretofore usual:

Extending below each pair of axle-boxes 7, at opposite sides of thebogie-truck, is a longitudinal beam 8, provided with a pair ofspring-holders 9, between which and the p spring-holding bracket d areplaced a pair of coiled bearing-springs 10. The ends of eachlongitudinal beam 8 pass through the lower slotted ends of a pair ofinverted-stirrupshaped supports 11, each of which extends upward betweenthe opposite sides of an axlebox 7 and the adjacent axle-box guides c,each end of each beam being recessed at its lower side, as indicated at12 in Fig. 1, and supported upon a V-shaped lug or bearing 13 on ayoke-piece 14, carried by the slotted lower ends of the correspondingsupport 11. Between the upper end of each support 11 and the top of thecorrespondingy axle-box 7 is placed a coiled spring 15, held in placellaterally by a socket-piece` 16 on the carrier and a socket 17 on thetop of the axle-box. The lower ends of the horn-plates 7) at each sideof the bogie-frame are connected together by a longitudinal rod or bar18.

Bogie-trucks constructed as hereinbefore described are speciallysuitable for use as motor-bogies for electrically-propelled vehicles.For this purpose the casing 19, carrying the field-magnets of eachelectric motor, may, as indicated in Figs. 1, 2, and 3, be eachjournaled at one end upon one of the .wheel-axles 20 and be supported atthe other end by means of lugs 21, that are carried by the casing 19 andbear upon springs 22, carried by bearingplates 23, held by bolts 24,suspended from the top-plate f of the bogie-truck, the motorarmaturebeing geared to the axle in the usual way. The springs 22 may, as shown,vconveniently be of the kind known as Spencers No.
